Hi everyone! New here would love to learn more and really need help. Recently I just bought what I was told was a Maze Brain. It has been stung by another coral of some sort while in the shops care. I purchased it for $25 and was told that it would heal and be ok or they would cut off the dead piece for me right then. I said no to the cutting because I asked them if it would live either way and the guy told me yes and it might even try to grow back over the old dead skeleton. Is this true or did I just buy a lost cause? What, if anything could I do to reverse this? The pic on the left was taken last night at around 5 pm. The middle was taken at around 11.30 pm and the last was taken today at 5 pm. Thanks for any help and advice I can get.
